CLOSUBE FOR BOTTLES.

Application filed Maroh22, 1923. vSerial No. 626,911.

To all whom t may concern.'

Be it known that we, CHARLES W. Toom and FREDERICK B. LA FORCE, citizens of `the United States, residing at Syracuse, in thc 5 county of Onondaga and State of New York, and Washington, in the District' of Colum bia, respectively, have invented certainnew and useful Improvements in Closures for Bottles; and we do hereby declare the fol- 1o lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same', reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

. This invention relates to closures for boti tles, jars, or the Ilike and, while having special reference to closures for milk bottles of the well-known commercial type, is obviously not limited in its application thereto.

An object of the present invention is to provide a closure of such material and form as will eiiectually close the top of such a jar or bottle against the accidental discharge of the contents and to protect the lip of the bottle from contamination and also pro-A tect the contents'of the jar from contamination through contact with the closure itself.

A further object of the invention is Ato provide a closure composed Vcfa sheet of material of such nature that it is softened by heat and` rigidied by cooling, at the same time adhering to the jar or bottle where heated, for the purpose of effecting a seal, the rigidifying material being odorless and tasteless to prevent contamination of the contents.

A further object of the invention is to provide an over all covering or cap for bottles, or other containers, which have already been sealed, the covering being 4composed of a Sheet of a paper in which'the rigiditying material has been incorporated, so that it may be shaped by heatl and pressure,and .upon cooling will retain its Shape and position, without employing' any other agency, as wire for exam le, to` hold it in place.

With these and) other objects in view, the invention comprises certain novel parts, elements and textures and physical and chemical properties applied as shown in the drawings herewith and claimed herein. i

In the drawings: f

Figure l shows a conventionalmilk bottle with the top or closure of the present invention applied thereto in sealed condition, part being broken away to show therelation of the closure to the-bottle.

Figure 2' is a transverse sectional vlew `through the lip of the bottle and closure, as taken on 'line 2-2 of Figure 1.

Figure Sis a sectional view through the neck of the bottle, showing the lower edge of the closure applied thereto, seen in inverted plan. l v v v Like characters of referenceindicate oorresponding parts throughout the Several views. i p v i The present invention comprises thelshape and form of the closure as applied to the bottle but more especially `and `particularly the structure of the closure itself.' `In its structural aspect the closure comprises a further described and sheet, 10, which covers over the top or openling or lip,

11,l of a bottle yshown kconventionally at :12. The material ofthe 'top which is of'sheet form is crimped downwardly along the lip,'1l, and under the 11p against the bottle at the neck, `12, so proportioned'that the outstanding folds from the crimping are laid down upon the surface of that part of the material engaging against the neck to form, if desired, a continuous seal as indicated at Figure 3.y This continuous seal is represented by the several segmental sections, 13, which abut one with the other'about theneck, 12, with the folds,

1 4, iiattened down upon these segmental sections, 13.' t l For the purpose of making a seal -between the segmental sections, 13, and the neck, l2,

or for maintaining the folds, 14, in such folded position, it is necessary that the ma.

terial of thel cap be such as to respond to the requirements. For this purpose, a sheet of-material is emlpoyed analogizing paper in that it is preferably made of paper stock, but into which or with which has been incorporated in any manner an odorless and tasteless resin. Preferably this resin is the resin resulting from the reaction of phenol with furfural. This resin is known and the ,present use'is one of its utilities. The pervantage centage et resin incorporated with the paper pulp depends upon the required rigidity; 'lhe-resiii referred to is odorless and tastelless so that the sheet of impregnated material may 'come directly in contact with the contents of the jar, as for instance milk, and will have no contaminating eiect theren on. 'lhe resin referred to has a further ado having once been fused by heat and rigidifled, it will not again ruse, so that once sealed in this manner, the top will not be released accidentally orotherwise by coming in contact with a hot surface or heat applied in any Way. Merely as a matter of illustration, it may be stated that the fur? iural resin is introduced into the beater with the paper pulp and thoroughly incorporated therewith, so that it becomes a part of the paper sheet. '.lhis urfural resin fuses at a temperature approximately 150 C., and' it is only necessary that the paper containing this resin be dried at a temperature lower than this. Dried at lesser temperature, `the resin maintains its comminuted condition incoporated in the material of the paper. Applying heat thereto, however, causes t e comminuted resin to fuse, forming when cooled asolid rigidied mass. By incorporating a larger percentage of the resin in the (paper, the-heating will cause the ca to a ere to the neck of the bottle, e'ectua ly excluding air from the contents of the bottle, and retaining the contents within the bottle. llt isobvious that the heat necessary for the purpose of fusing is above 150 C., but it is also obvious that the heat will be applied only momentarily, long enough to heat vthrough the thickness of the paper, which, upon its discontinuance will almost instantly rigidi Any other known material which wil perform the function required or desired in this case may be used in the present invention, which therefore in` cludes not only the form, construction and application of the cap, structurally speaking, but a paper-like material for a cap, with the resin incorporated therein. l
